3.2 Intended use
The product described is a hand-held electric angle grinder. It is designed for cutting and grinding metal and
mineral materials without use of water. It may used only for dry cutting / grinding.
The tool may be operated only when connected to a power supply providing a voltage and frequency in
compliance with the information given on its type plate.
• The power tool may be used for cutting, slitting and grinding mineral materials only when equipped with
the corresponding guard (optional accessory).
• A dust removal hood together with a suitable Hilti vacuum cleaner must be used for working on mineral

3.4 Starting current limitation
The electronic starting current limiter reduces the starting current drawn by the power tool and thus prevents
the mains fuse blowing. It also allows the power tool to start smoothly, without a jolt.
3.5 Constant-speed electronics
Electronic speed control keeps running speed almost constant irrespective of whether the power tool is
idling or running under load. Constant running speed helps ensure maximum efficiency.
3.6 Active Torque Control (ATC)
The electronics detect potential stalling of the disc and prevent further rotation of the arbor by switching off
the tool.
If the ATC system has been triggered, restart the tool. Do this by releasing the on/off switch and then
pressing it again.
Note
If the ATC system malfunctions, the power tool will run only at greatly reduced speed and with greatly
reduced torque. Have the tool checked by Hilti Service.
3.7 Current-dependent overload protection
The current-dependent motor overload protection system monitors current input and thus protects the tool
from overloading.
If the motor is overloaded through application of excessive working pressure, the power tool’s performance
drops noticeably or it may stall completely. A standstill should be avoided.
3.8 DC-EX 230/9" dust hood for cutting, with carriage (accessory) 2
The power tool may be used for cutting and slitting work on mineral materials only when fitted with a dust hood.
CAUTION Use of this hood for working on metal is prohibited.
